Problems solved by technology

[0003] However, for pluggable water tanks, that is, water tanks that can be detached from mobile platforms such as drones, each time the water tank is plugged and unplugged, it is easy for air to enter the pipes of the sprinkler system.
When there is air in the pipeline of the sprinkler system, especially in the pump chamber, the outlet pressure of the sprinkler system is difficult to reach the above pressure threshold, so that the pressure relief valve cannot be pushed back to exhaust
At this time, it is necessary to manually open the pressure relief valve to discharge the gas in the spraying system, which

Abstract

Disclosed are a pump assembly (100), a spraying system (10), a moving device (1000) and a spraying method thereof. The pump assembly (100) includes a water pump device (110), a liquid distributor (120) and a liquid storage and exhaust structure (130). The liquid storage and exhaust structure (130) is in communication with a liquid dispenser (120). The liquid storage and exhaust structure (130) isused to store the liquid flowing into the liquid distributor (120) or supply the stored liquid to the liquid distributor (120) and can discharge gas in the pump assembly (100).

Description

technical field [0001] The invention relates to the technical field of pump assembly equipment, in particular to a pump assembly, a spraying system, a mobile device and a spraying method for the mobile device. Background technique [0002] With the continuous improvement of environmental protection requirements, people have higher and higher requirements for anti-leakage of spraying systems when spraying is stopped. Due to the effect of gravity, when the existing spraying system stops spraying, the spray head usually has a problem of liquid dripping, that is, there is a problem of dripping, which causes the waste of liquid medicine and pollutes the environment. In order to solve the problem of dripping from the nozzle after the spraying is stopped, a normally closed pressure switch, namely a pressure relief valve, is usually installed on the nozzle. When the outlet pressure of the spraying system is greater than the pressure threshold, the spraying system will start spraying...
